Sorry guys, I've been busy drinking beer and peeling brussel sprouts, so hadn't noticed the drawing had gone, so just refreshed it as it was. I've had a look at the link Why Me, and found your 3-in/50, but it seems a bit short in the tube, compared to the photo's. I have had some trepidition with this one, as I'm on 'hallowed ground' with the USN WWII; so I've basically studied all previous SB drawings of that period and taken what looks like the same equipment; but I have to admit that the rear aa, which is supposed to be a 40mm twin, might not correspond to what is now appearing on the USN parts sheet; and with the 3-in/50 I used, I did shorten the tube as it loooked a bit overlong. I realise this might start a 'frank exchange of views', but I'm happy to let folk put in their advice/suggestions on this one
Thanks again graham for the link, and there is more mileage in this design - one I really like
